Oracle and SUN A few weeks ago, I stubbed my toe on my old Sun Ultra 5 as it sat there lifeless and unused in my apartment. Once my primary desktop, the envy of my geek friends, and a way to woo the ladies, its glory days have long since passed. As much as I would like to let it live out its days looking sexy and taking up space, I live on the island of Manhattan, where space is a premium. Since I can't charge it rent, I decided I'd better use it or lose it. But what to use it for? What operating system would I run on it? Solaris? What about Linux? FreeBSD? NetBSD? OpenBSD? They all run on the SPARC platform, so I thought why not do a quick review.

RE: Ultra 10 scrolling speed

The OpenBoot PROM monitor operates even when the main system is halted. Scrolling is done without DMA - it updates the frame buffer with interrupts off. For faster scrolling, run a GUI or use /dev/ttya. When logged in at the raw console, I type 'cat', ESCape [ 2 4 r Enter Control-D. That causes scrolling to happen 24 lines at a time instead of one line at a time. Return to "normal" with ESCape [ r Enter Control-D.
